BACKPACK BLOWER
PROBLEM TO BE SOLVED: To provide a backpack blower capable of enhancing the cooling performance for an engine inside a cover while promoting silent operation.SOLUTION: The present invention relates to a backpack blower 100 comprising: a blower unit 1 having a casing 11, an impeller 12, an engine 13, and an outer cover 15; and a backpack frame 2. The casing 11 is located between a back panel 21 and the engine 13, a suction port S1 is open at an engine-side side part, and a cylinder part 13a is disposed above a crank case part 13b. The backpack blower further includes: an air intake S2 in a lower part of the outer cover 15; a first air guide part 16a which extends vertically in the outer cover 15 and guides air from the air intake S2 to an upper region in the outer cover 15; and a second air guide part 16b which is provided so as to cover a top of the engine 13 and passes the air guided by the first air guide part 16a through the circumference of the cylinder part 13a, and guides the air to the suction port S1.SELECTED DRAWING: Figure 1
【課題】静音化を図りつつ、カバー内のエンジンに対する冷却性能を高めることが可能な背負式ブロワを提供する。【解決手段】ケーシング１１、羽根車１２、エンジン１３及びアウターカバー１５を有するブロワユニット１と、背負フレーム２とを備えた背負式ブロワ１００であって、ケーシング１１は、背板部２１とエンジン１３間に配置され、エンジン側の側部に吸気口Ｓ１が開口され、シリンダ部１３ａはクランクケース部１３ｂの上方に配置され、アウターカバー１５の下部の空気取り込み口Ｓ２と、アウターカバー１５内にて上下方向に延び空気取り込み口Ｓ２からの空気をアウターカバー１５内の上部領域に導く第１導風部１６ａと、エンジン１３の上部を覆うように設けられ第１導風部１６ａによって導かれた空気をシリンダ部１３ａの周囲を通過させて吸気口Ｓ１に導く第２導風部１６ｂと、含んで構成される。【選択図】図１
